Summary
REDAXO from 5.18.0 before 5.21.4 contains a stored cross-site scripting vulnerability because rex_media_service moves uploaded SVG files into the public media folder before sanitizing them. Authenticated users with mediapool upload rights can race the sanitizer or exhaust memory limits to leave script-laden SVGs publicly served, executing scripts in victims' backend sessions.
